Tambourhinoceros’ co-founders and Oh No Ono members Aske and Kristoffer immediately lost their hearts to the sound back in 2009 when they heard it for the first time. A fan of Oh No Ono had arranged for the sisters to play a couple of songs at the stairs of the venue after a concert. Kirsten & Marie’s music actually kick-started the idea of founding a new record label led by artists and dedicated to the love for music: Tambourhinoceros. The EP Kirsten & Marie became its first release in May 2010.
